Applicstion M February 21, mos. Serial No. 417,0.

To all whom it may conccrn:

Be it; known that I, FRrrz Ksssnir, a citizen of the United States of America, residin er, Highland, in the county of Madison an State of Illinois, have invented certain new useful lmprovemenis in (lsn Polishing lllschines, of which she following is s full, clear, slid execs des cri sion,freierence being hard to the accompanyingdmwinggiorming.

pert. of this specification. n v My invention relates s! whims 'i' poiishiri the ends ofsheet metal csnsisndzeon-i temp sizes improvemenhs upon llhoccn polishfor adjustment independently of eac other;

also otherfeetures of construction that render the mschine more eficient in op emtion.

-i igure I is s. to or len view of my improved mschine' A i'g. l is a. view partly in side elevation and peril 'in vcrtics section of she machine. Fig. ll; ticel cross section taken on line I I-III, Fig 11. r

in the eccom snying drawings: 1 dos notes the main rrsme of my machine whi c h is sup orted by legs 2. At the receiving end A of t c machine 18 an extension frame 3, see

Fine. 1 and II, that furnishes ssupporl; for

o shaft 4 equipped. with s rocket wheels 5 and i "the delivery end B of t is machine is an extension frame 6 that furnishes a support for a shaft 7 equipped with s rocket Wheels 8. The sprocket wheels 5 an 8 support an endless conveyor consisting of 21 pair of chains 9 end cross bars 10 and which is adapted to irnvel' above the main frame 1 and return henesth 'seid main frame. The endless carrier sdepted to receive trays C in which the cons to be polished are placed and which are hers while the trays are being conducted from che receiving end to the delivery end of the machine.

@ne of the sprocket Wheel shafts that serve to drive the endless carrier of the machine, for instance that 7, is provided with a, worm hr th machine, being :Iimm lr v ls it lriction'drive wheel '17" whioh 'n ar-' 'rp contact with-tghofocs ol'thi friction dish 'l-lgkandis-adspted' to; power from theMve shaft to tho'driven shall; 13.

'exfiends transve y in the misin frame of the machine. This shill; rod; is provided at one end with suitable means for rotatin it, such as a crank handle 19,.and it is fit at its other end to a. shift disk 20 tlmtis loosol associated with, the friction wheel 17- and-is sdspred to shiftsaid frictiem' wheel on tho 4 drive shaft 15 toward and awe from the sxisoi the friction disk 14 when l} o shiit rod 18 is oplersted;

By t

eed of operation of the endless carrier of S t e machine, inasmuch as thecarrier will be" driven at odiminished sad when the friction wheel 17 is remote om the-'axis oi the friction disk 14 and at a greater speed when e construction just described,l 811i enabled to provide for any desired degree of the friction wheel is moved closer tothe axis of said disk.

At the sides ofthe main frame of the mm chine are verticsl guides 21.which are atrsnged in pairs.

22 are vertically disposed'lift plates oper s able in the sides 21 and independently of each other, t are be" preferab y two of said lift plates at each si eof the machine and" esch'plste being mated with lghe plate that is directly op osite .to it at the other side of the rinschine. sch lift plate 22 has secured to it at its upper end a guide rail'23 which is in dependent of the guide mil carried by the ot er lift plate at the some side of the machine. Y

24 and 26 are polishing brush holdors'that have secured to the lower sides brushes 25 and 27, the former of which is an initial or damp polishing brush while the latter is b iio final or dry polishing brush. The brush holder 24 operates upon the guide rails 23 nearest to the receiving end of the machine while the brush holder 26 operates upon the guide rails 23 nearestthe delivery end of the machine.

28 designates a connecting member to which the brush holders 24 and 26 are pivotally united at 29 and 30, thereby providing for independent rise and fall motion of said brush holders with their brushes.

31 is an operating rod attached to the connecting member 28 and by which, upon the application of suitable power thereto, said connecting member and the brush holders may be reciprocated longitudinally of the machine, during which action the brush 1 holders travel upon the guide rails 23.

To provide for the raising and lowering of the guide rails 23 in order that the brush holders and their brushes may be so )ported at varying elevations above the end ess cari rier of the machine according to the heights of the cans being conducted upon said carrier and being polished, I employ the following mechanism by which the lift plates 22 are raised and lowered. Each lift plate is provided with an interiorly screw-threaded are provided with worms 37 that mesh with the worm Wheels- 85 of'the lift screws The operating shafts are provided with suitable ,means by which they may be rotated, such as hand wheels 38, and they are adapted to perform the o eration of raising and lower ing the pairs of ift plates 22 which are op posite to each other transversely of the machine so that each pair of said lift plates may be raised and lowered independently of the other pair of said plates.

By providing the separate and independent means described for raising and lowering the lift plates 22 arranged in pairs transversely of the machine and the brush holder guide rails 23 carried by said lift plates, I so support the brush holders that they may be held irrespective of each other at the desired elevations above the tops of the cans being polished. Therefore, if one brush becomes worn, more than the other brush, the brush holder may be so lowered to create the proper contact thereof with the cans to be polished while the other brush holder is upheld at a greater elevation for its polishing action. It will also be seen that the provision of means for upholding the brushes at different elevations makes it possible to vary the degreeof pressure of one brush upon the cans relative to the pressure of the other brush as may be desirable for either scrubbing action by the damp brush or polishing action by the dry brush.

To provide for the delivery of the polishing substance that is usedin my machine as it falls from the cans and the brushes into the machine after it has been utilized, I amploy a collecting device for such substance.

This collecting device comprises a suction flue 39 which has communication with the interior of the main frame of the machine into which the polishing substance enters. This section llue is preferably equipped with a suction fan not -shownzand by which the polishing substance is drawn into the flue and carried to any desirable point of delivery to be removed from the machine.

I claim:

1. In a can polishing machine, a main frame, pairs of vertically movable supports fitted to said frame, one pair of supports being arranged forward of the other pair of supports, means for independently raising and lowering each pair of said supports, brush holders movably mounted upon said paired supports, and means for reciprocating the brush holders upon the stantially as set forth.

2. In a can polishing machine, a main frame, a carrier whereby the cans to be polished may be conducted through said machine, pairs of vertically movable brush holder supports fitted to said frame each pair of supports being susceptible of vertical movement independent of the other pair of supports, means for independently raising and lowering each pair of said supports,

brush holders movably mounted upon said paired supports, and means for reciprocating the brush holders upon the'supports, substantially as set forth.

3. In a can polishin machine, a main frame, pairs of brush holder lift'plates fitted to said frame, guide rails carried by each pair of said lift plates and arranged independent of each other, means whereby said lift plates may be raised and lowered in pairs supports, sub- I independent of any other pair, brush holders movably mounted upon the pairs of guide rails, and means for reciprocating the brush holders upon the supports, substantially as set forth.

4. In a can polishing machine, a main frame, a carrier whereby the cans to be polished may be conducted through. said machine, pairs of lift plates fitted to said frame, guide rails carried by. said lift plates and arranged independent of each other, means whereby said lift plates may be raised and lowered in pairs independent of any other pair, and brush holders movably mounted upon the pairs of guide rails, substantially as set forth.
